x = 25
-4 * 25 = -100 + 88 = -12

since adding a negative number to a positive one is the same as subtracting both positives this is correct

Here, we are basically solving for x to find it's value: 
Subtract 88 from both sides: 
[tex]-4x + 88-88 = -12-88 [/tex]

Now we have: 
[tex]-4x=-100 [/tex]

divide both sides by -4
x=25 

Final answer x=25

To check: 
Plug in 25 for x: 
-4(25) + 88 = -12
-12=-12 TRUE.
